[PHYSX] PhysX.PxsContext.contactManagerDiscreteUpdate spikes when small amount of rigidbodies are being spawned
To reproduce:
1. Open attached project
2. Press play and go to profiler
3. In the game press Respawn button
4. In the profiler check PhysX.PxsContext.contactManagerDiscreteUpdate
Actual result: Huge spikes of physics appear
Expected result: There should be no spikes
Reproduced with: 2019.1.8f1; 2019.2.0b7; 2019.3.0a8
Can't check on 2017.4 and 2018.4 due to errors.

Resolution Note:
The time taken here is to fetch triangles that may be potentially overlapping with the bounds of the bodies. Apparently, this is a very costly process in PhysX, and the only real way to bring it down in this project is to reduce the resolution of the terrain heightmap.
